GRUVEBUS - GREEN automatic The blue model is limitedDeep inside the Arctic archipelago of Svalbard, Norwegian miners have worked seams of ultra pure anthracite for over a century. Gruvebus takes its nameand its toughnessfrom that legacy. Quenched mining grade steel the 40 mm case is fired with high carbon anthracite from Svalbards Mine 7, then salt quenched, boosting hardness from about 192 HV to 224 HV ( 17 % harder than standard 316 L) for better scratch and impact resistance.
